Objective To correlate vWF expression in the endothelium of transitional pulmonary arterioles from lung biopsy in patients with pulmonary hypertension (PH) secondary to left-to-right shunt congenital heart defects (CHD). The results will be compared to vWF expression in peripheral venous plasma pre-operatively and the early post-operative outcome. Methods Consecutive 70 cases of left-to-right shunt congenital heart defects were involved in the study, the age ranged from 4 months to 63 years. Pulmonary systolic pressure/systemic systolic pressure (Pp/Ps) was calculated from Swan-Ganz floating catheter monitoring before corrective operation. PH was found in 62 cases, with slight PH in 16, moderated PH in 24 and severe PH in 22. Non-PH in 8 cases. Twenty-six cases of non-heart and lung disease were involved in as control. Lung biopsy tissue was stained for routine pathologic classification and quantitative vWF expression, with testing vWF in the peripheral venous blood. Post-operative complication was noted. Results There was a statistically difference of vWF expression in the endothelium of pulmonary transitional arterioles between PH group and non-PH group, with reducing intensity in order of non-PH, slight Ph, moderate PH and severe PH. A negative relationship was statistically noted between Pp/Ps and vWF expression in the arteriole endothelium (=61.88-33.30x, r=-0.701, P

With the Meta-analysis method, the clinical efficacy of acupuncture and other regular methods for aphasia was evaluated, and the acupoints selection for aphasia was explored. The acupuncture literature of clinical randomized control trials for aphasia published in CNKI, WANFANG, VIP and CBM database was searched; the statistical analysis of clinical efficacy of acupuncture and other regular methods for aphasia was performed by using software Revman 5. 2 provided by Cochrane library. A file of Microsoft Excel was established to perform the analysis of acupoints selection based on frequency analysis method, so as to summarize the characteristics and rules. Totally 385 articles were searched, and 37 articles those met the inclusive criteria was included, involving 1,260 patients in the acupuncture group and 1 238 patients in the control group. The Meta-analysis results showed OR = 3.82, 95% Cl [3.01, 4.85]; rhombus was located on the right side and the funnel plot was nearly symmetry, indicating the treatment effect of the acupuncture group for aphasia was superior to the control group (Z = 11.04, P < 0.000 01). The frequency-analysis results showed that the frequency of acupoints from top to bottom was Lian-quan (CV 23), Tongli (HT 5), Yamen (GV 15), Jinjin (EX-HN 12), Yuye (EX-HN 13), Baihui (GV 20), Yuyan II, Yuyan I and Yuyan III. The frequency of meridians from top to bottom was the governor vessel, extra channels, conception vessel, heart meridian and large intestine meridian. It is concluded that the clinical efficacy of acupuncture combined with speech rehabilitation training and medication treatment for aphasia is superior to that of speech rehabilitation training and medication treatment alone. The clinical treatment for aphasia focuses on its local effect; the main acupoints are in the head and face, and the meridians are governor vessel, extra channels and conception vessel.

Objective To explore the reliability and validity of the Chinese version of the 36-item Short Form Health Survey (SF-36) for evaluating the health-related quality of life of patients with chronic soft tissue pain, (CSTP). Methods Two hundred and ten CSTP patients were rated with the SF-36 and the Medical Outcomes Study Pain Measurement (MOSPM) instrument and retested 2 weeks later. The internal consistency, test-retest relia-bility and parallel validity of the SF-36 were analyzed. Results The SF-36 showed good internal consistency and test-retest reliability. Most repeated reliability internal correlation coefficients were between 0.44 and O. 66 (P≤0.01) except that of the SF sub-scale of the SF-36, which was O. 336 (P≤0.05). All the internal consistency Cronbach's a coefficients were >0.70. In the assessment of validity, there was significant correlation among all eight sub-scales of the SF-36, and between items 4-11 and total MOSPM scores. The correlation coefficients were between -0.145 and 0. 635 (P≤0.05 or P≤0.01), except between GH of the SF-36 and item 4 of the M OSPM (pain in-fluence on walking) and between MH and item 10 (pain influence days). Conclusion The Chinese version of the SF-36 has good reliability and validity in assessing the health related quality of life of CSTP patients.

An enzyme-displaying yeast as a whole-cell biocatalyst seemed an alternative to immobilized enzyme, due to its low-cost preparation and simple recycle course. Here, we tried to use a recombinant Pichia pastoris displaying Candida antarctica lipase B (CALB) to catalyze the synthesis of short chain flavor esters in n-heptane. We studied some major influential factors of esterification reactions, such as carbon chain length of the substrates, alcohol structure, enzyme concentration, substrates concentration, molar ratio of the substrates. The acid conversions were determined by titration and gas chromatography analysis. About ten kinds of esters were synthesized successfully, and the acid conversions of eight esters reached as high as 90% after reaction for 6 h. The result also indicated that ethanol and hexanoic acid were the most suitable substrates for this whole-cell catalyst. Under the optimal reaction conditions (the amount of lipase 20 g/L (306.0 U/g-dry cell), hexanoic acid concentration 0.8 mol/L, the molar ratio of hexanoic acid to ethanol 1:1.1), hexanoic acid conversion reached 97.3% after reaction for 1.5 h. To our knowledge, the CALB-displaying P. pastoris whole-cell biocatalyst showed good tolerance for high substrates concentration and exhibited high reaction rate on esterification of short chain flavor esters among the present enzyme/cell reported. Thus, CALB-displaying P pastoris whole-cell biocatalyst was promising in commercial application for flavor esters synthesis in non-aqueous phase.
